Mark (b), If the question can be answered with the help of statement II, alone,
Mark (c), If both, statement I and statement II are needed to answer the question, and

If the selling price were to be increased by 10%, the sales would reduce by 10%. In what ratio would profits change?

II. The cost price increased 10%.
Answer & solution
- A
a
b
- C
c
- D
d
P = (SP – CP) x Sales. From the data given in the question we can figure out that P1 = (1.1SP – CP) x
0.9Sales. Hence To find this ratio we need to eliminate the variables CP & SP. This can only be done if in the denominator, CP is replaced by 1.1CP. In other words, if the CP increases by 10%, as in that case our ratio will be = 1.01. Hence only Statement II is required to answer the question.
